Providers register routing policyUsed for planning, debugging and

generating backbone router configshttp://www.radb.net/


What is the Routing Registry?Can be used by anyone worldwide

debugging configuring engineering routing addressing


What is the Routing Registry? contact names, email addresses and

telephone numbers for an AS routing policy for an AS (what other

ASes does it connect to, which routes do they exchange)

information about routes (most important is which AS originates the route)

several other types of information


What happens if I don’t use a database?

Routing Horror Stories AS7007

filtering would have prevented this announcing bogus routes


So, I need to use the database because…..

Filters generated off the IRR protect against inaccurate routing information

Makes troubleshooting and debugging easier

Keep track of policySecurityFilter! Filter! Filter!!


Why Bother with all of this?View of global routing policy in a single

cooperatively maintained databaseto improve integrity of Internet’s

routinggenerate router configs

protect against inaccurate routing info distribution

verification of Internet routing


Why Bother using the database (con)

Many providers require that you register your policy peering customer relationship

Route Servers


What is Internet2 going to do?

Merit is setting up a database for I2 community source: I2 register Internet2 routing policy and

informationWill be RPSLUp by end of July

route objects, AS-MACROScurrently RIPE-181moving to RPSL

more policy control


What is RPSL?Routing Policy Specification

LanguageDesigned to replace current

language (RIPE-181)Enhanced and more generalized


How does the language work?

Object-orientedExpress policy in objects
